When he doesn't go into his "Cipher Mode" he is very fun loving and easy to be around but once he is in the mode he is the deadliest person in the room with his advaned martial art skills. He once put Yoshirou on the ground in a hold position before Yoshirou could blink or react. Which is why Cipher 20 is referred to the fastest Cipher ever created. His speed is exceptional and is able to run at speeds of a 100 meter dash in 7 seconds.
Bioengineered to be faster, stronger, and endure much longer than most, they created Cipher 20 who was literally able to run at speeds exceeding 30 miles at a jog and push the boundries to 50 miles for an outlasting run. However this being said he was considered the fastest Cipher and Taiidan ever born or created. He was well known to be able to put his enemies on the ground before they could react to his speed. He also seemed to have precognitive abilities and was able to dodge fire because of it. This was due to an implant the UGI created that once a gun was fired he could react to the gun the moment he heard it. (Much like spider sense)
